The word "possession" denotes such a group of facts. Hence, when we say of a man that he has possession, we affirm directly that all the facts of a certain group are true of him, and we convey indirectly or by implication that the law will give him the advantage of the situation. Contract, or property, or any other substantive notion of the law, may be analyzed in the same way, and should be treated in the same order. The only difference is, that, [215] while possession denotes the facts and connotes the consequence, property always, and contract with more uncertainty and oscillation, denote the consequence and connote the facts. When we say that a man owns a thing, we affirm directly that he has the benefit of the consequences attached to a certain group of facts, and, by implication, that the facts are true of him. The important thing to grasp is, that each of these legal compounds, possession, property, and contract, is to be analyzed into fact and right, antecedent and consequent, in like manner as every other. It is wholly immaterial that one element is accented by one word, and the other by the other two. We are not studying etymology, but law. There are always two things to be asked: first, what are the facts which make up the group in question; and then, what are the consequences attached by the law to that group. The former generally offers the only difficulties.

Hence, it is almost tautologous to say that the protection which the law attaches by way of consequence to possession, is as truly a right in a legal sense as those consequences which are attached to adverse holding for the period of prescription, or to a promise for value or under seal. If the statement is aided by dramatic reinforcement, I may add that possessory rights pass by descent or devise, as well as by conveyance, /1/ and that they are taxed as property in some of the States. /2/

We are now ready to analyze possession as understood by the common law. In order to discover the facts which constitute it, it will be found best to study them at the moment when possession is first gained. For then they must [216] all be present in the same way that both consideration and promise must be present at the moment of making a contract. But when we turn to the continuance of possessory rights, or, as is commonly said, the continuance of possession, it will be agreed by all schools that less than all the facts required to call those rights into being need continue presently true in order to keep them alive.

To gain possession, then, a man must stand in a certain physical relation to the object and to the rest of the world, and must have a certain intent. These relations and this intent are the facts of which we are in search.

The physical relation to others is simply a relation of manifested power coextensive with the intent, and will need to have but little said about it when the nature of the intent is settled. When I come to the latter, I shall not attempt a similar analysis to that which has been pursued with regard to intent as an element of liability. For the principles developed as to intent in that connection have no relation to the present subject, and any such analysis so far as it did not fail would be little more than a discussion of evidence. The intent inquired into here must be overtly manifested, perhaps, but all theories of the grounds on which possession is protected would seem to agree in leading to the requirement that it should be actual, subject, of course, to the necessary limits of legal investigation.

But, besides our power and intent as towards our fellow-men, there must be a certain degree of power over the object. If there were only one other man in the world, and he was safe under lock and key in jail, the person having the key would not possess the swallows that flew over the prison. This element is illustrated by cases of capture, [217] although no doubt the point at which the line is drawn is affected by consideration of the degree of power obtained as against other people, as well as by that which has been gained over the object. The Roman and the common law agree that, in general, fresh pursuit of wild animals does not give the pursuer the rights of possession. Until escape has been made impossible by some means, another may step in and kill or catch and carry off the game if he can. Thus it has been held that an action does not lie against a person for killing and taking a fox which had been pursued by another, and was then actually in the view of the person who had originally found, started, and chased it. /1/ The Court of Queen's Bench even went so far as to decide, notwithstanding a verdict the other way, that when fish were nearly surrounded by a seine, with an opening of seven fathoms between the ends, at which point boats were stationed to frighten them from escaping, they were not reduced to possession as against a stranger who rowed in through the opening and helped himself. /2/ But the difference between the power over the object which is sufficient for possession, and that which is not, is clearly one of degree only, and the line may be drawn at different places at different times on grounds just referred to. Thus we are told that the legislature of New York enacted, in 1844, that any one who started and pursued deer in certain counties of that State should be deemed in possession of the game so long as he continued in fresh pursuit of it, /3/ and to that extent modified the New York decisions just cited. So, while Justinian decided that a wild beast so [218] badly wounded that it might easily be taken must be actually taken before it belongs to the captors, /1/ Judge Lowell, with equal reason, has upheld the contrary custom of the American whalemen in the Arctic Ocean, mentioned above, which gives a whale to the vessel whose iron first remains in it, provided claim be made before cutting in. /2/

We may pass from the physical relation to the object with these few examples, because it cannot often come into consideration except in the case of living and wild things. And so we come to the intent, which is the really troublesome matter. It is just here that we find the German jurists unsatisfactory, for reasons which I have already explained. The best known theories have been framed as theories of the German interpretation of the Roman law, under the influence of some form of Kantian or post-Kantian philosophy. The type of Roman possession, according to German opinion, was that of an owner, or of one on his way to become owner. Following this out, it was said by Savigny, the only writer on the subject with whom English readers are generally acquainted, that the animus domini, or intent to deal with the thing as owner, is in general necessary to turn a mere physical detention into juridical possession. /3/ We need not stop to inquire whether this modern form or the [Greek characters] (animus dominantis, animus dominandi) of Theophilus /4/ and the Greek sources is more exact; for either excludes, as the civilians and canonists do, and as the [219] German theories must, most bailees and termors from the list of possessors. /1/

The effect of this exclusion as interpreted by the Kantian philosophy of law, has been to lead the German lawyers to consider the intent necessary to possession as primarily self-regarding. Their philosophy teaches them that a man's physical power over an object is protected because he has the will to make it his, and it has thus become a part of his very self, the external manifestation of his freedom. /2/ The will of the possessor being thus conceived as self-regarding, the intent with which he must hold is pretty clear: he must hold for his own benefit. Furthermore, the self-regarding intent must go to the height of an intent to appropriate; for otherwise, it seems to be implied, the object would not truly be brought under the personality of the possessor.

The grounds for rejecting the criteria of the Roman law have been shown above. Let us begin afresh. Legal duties are logically antecedent to legal rights. What may be their relation to moral rights if there are any, and whether moral rights are not in like manner logically the offspring of moral duties, are questions which do not concern us here. These are for the philosopher, who approaches the law from without as part of a larger series of human manifestations. The business of the jurist is to make known the content of the law; that is, to work upon it from within, or logically, arranging and distributing it, in order, from its stemmum genus to its infima species, so far as practicable. Legal duties then come before legal [220] rights. To put it more broadly, and avoid the word duty, which is open to objection, the direct working of the law is to limit freedom of action or choice on the part of a greater or less number of persons in certain specified ways; while the power of removing or enforcing this limitation which is generally confided to certain other private persons, or, in other words, a right corresponding to the burden, is not a necessary or universal correlative. Again, a large part of the advantages enjoyed by one who has a right are not created by the law. The law does not enable me to use or abuse this book which lies before me. That is a physical power which I have without the aid of the law. What the law does is simply to prevent other men to a greater or less extent from interfering with my use or abuse. And this analysis and example apply to the case of possession, as well as to ownership.

Such being the direct working of the law in the case of possession, one would think that the animus or intent most nearly parallel to its movement would be the intent of which we are in search. If what the law does is to exclude others from interfering with the object, it would seem that the intent which the law should require is an intent to exclude others. I believe that such an intent is all that the common law deems needful, and that on principle no more should be required.
